Truth:

Medicare Part B provides coverage for vitamin D testing when it is deemed medically necessary by a physician. This coverage applies to outpatient procedures conducted in a physician’s office or laboratory, particularly for patients with specific conditions such as Crohn’s disease or chronic kidney disease. However, it is important to note that routine screening for vitamin D levels is not covered under Medicare. This means beneficiaries should ensure their testing is medically necessary to avoid unexpected costs.

TIP/Trick:

Once a beneficiary is diagnosed with vitamin D deficiency, additional testing may be necessary to monitor the effectiveness of treatment. Generally, testing can be performed up to four times per year for vitamin D deficiency. Medicare limits how often a vitamin D test can be reimbursed, even when a patient has a covered diagnosis. If a deficiency is identified, a repeat test may be permitted after 12 weeks of replacement therapy. If the patient remains deficient and continues replacement therapy, additional follow-up testing may be allowed based on medical necessity.
